Product details
Overview
VOR1142A6 from Vishay Semiconductors is a DIP-6 packaged solid-state relay (SSR) with SPST normally open (Form A) configuration, GaAlAs IRED input and MOSFET output stage, 5300 VRMS isolation, 400 V load voltage rating, and 140 mA AC/DC continuous load current capability - used for bounce-free telecom switching and industrial control signal isolation.
For engineers reviewing the VOR1142A6 datasheet, VOR1142A6 pinout, VOR1142A6 application, or VOR1142A6 equivalent, key selection criteria include isolation voltage compliance (UL/cUL/VDE), on-resistance (22 Ω typ. in AC/DC mode), ambient temperature range (−40 °C to +100 °C), and DIP-6 through-hole package compatibility with legacy relay footprints.
Technical Context
The VOR1142A6 integrates an infrared LED driver stage optically coupled to a high-voltage MOSFET output switch, enabling galvanic isolation between control and load circuits. Its safety-rated insulation meets UL 1577 (5300 VRMS), DIN EN 60747-5-5 (VIORM = 890 Vpeak), and includes ≥7 mm creepage/clearance for DIP-6 packaging.
It operates in two configurations: AC/DC (140 mA IL, 22 Ω RON) and DC-only (270 mA IL, 5.2 Ω RON), with turn-on/turn-off times of 0.13 ms and 0.05 ms respectively at IF = 5 mA. Input requires only 0.27 mA typical forward current to activate the output switch.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5300 VRMS - enables safe operation across reinforced insulation barriers per UL/cUL/VDE standards |
| Load Voltage Rating | 400 V - supports direct switching of 230 VAC mains and 380 VDC industrial bus lines |
| Continuous Load Current | 140 mA (AC/DC), 270 mA (DC-only) - defines maximum steady-state current handling without derating |
| On-Resistance | 22 Ω (AC/DC), 5.2 Ω (DC-only) - determines I²R power loss and thermal rise under load |
| Turn-On Time | 0.13 ms (typ.) - ensures fast digital control response in automated test equipment |
| Ambient Temp Range | −40 °C to +100 °C - supports deployment in uncooled industrial enclosures and outdoor metering units |
| Input Forward Current | 0.27 mA (typ., turn-on) - allows direct drive from low-power microcontrollers without external amplification |
Pinout & Package
DIP-6 through-hole package with 7.62 mm lead pitch, 7 mm minimum creepage/clearance, and 0.4 mm minimum insulation thickness - compliant with IEC 60747-5-5 for safe electrical insulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (IRED) | Positive input terminal for GaAlAs infrared LED; requires series resistor for current limiting |
| 2 | Cathode (IRED) | Ground return path for input LED; referenced to primary-side control logic ground |
| 3 | No Connect | Internally unused; must remain floating - no PCB trace or component connection |
| 4 | Output Source (MOSFET) | High-side output terminal for AC/DC configuration; connects to load's positive rail |
| 5 | Output Drain (MOSFET) | Low-side output terminal for AC/DC configuration; connects to load's negative/return path |
| 6 | Output Common | Shared reference node for DC-only configuration; ties source and drain terminals internally |
Key Features
| Feature | Design Value |
|---|---|
| Bounce-free switching | Eliminates mechanical contact arcing and timing jitter - critical for precision instrumentation sampling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar solid-state relay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VOR1142B6 | SMD-6 surface-mount package; identical electrical specs and safety ratings | Requires reflow-compatible PCB layout; unsuitable for through-hole prototyping or legacy DIP sockets | Select when board space is constrained and automated SMT assembly is available |
| VO1263AD | Higher 600 V load voltage rating; 120 mA AC/DC load current; 30 Ω RON; same DIP-6 footprint | Better suited for 400 VAC industrial motor controls but lower current capacity limits use in high-load metering | Choose when higher voltage margin is prioritized over load current capability |
Compared with VOR1142B6 (SMD variant) and VO1263AD (higher-voltage, lower-current variant), the VOR1142A6 uniquely balances 400 V load capability, 140 mA AC/DC current, and DIP-6 through-hole compatibility - making it optimal for retrofitting electromechanical relays in field-deployed industrial hardware where manual assembly and serviceability matter.

FAQ
What is the maximum continuous load current rating for VOR1142A6 in AC/DC configuration?
The VOR1142A6 supports 140 mA continuous load current in AC/DC configuration, validated per IEC 60747-5-5 at Tamb = 25 °C and derated linearly above 25 °C per Figure 5 in the datasheet. At 100 °C ambient, the usable current drops to approximately 90 mA to maintain safe junction temperature and output safety power limits.
Does VOR1142A6 require an external current-limiting resistor on the input side?
Yes, VOR1142A6 requires an external series resistor on the anode (Pin 1) to limit IRED forward current to ≤50 mA absolute maximum. For typical 3.3 V or 5 V MCU GPIO drive, a 220 Ω to 470 Ω resistor ensures IF remains within 0.27–2 mA turn-on range while protecting the GaAlAs LED from overcurrent damage.
Can VOR1142A6 be used in DC-only mode, and how does its performance differ from AC/DC mode?
Yes, VOR1142A6 supports DC-only mode using Pin 6 as common terminal, delivering 270 mA continuous load current and 5.2 Ω typical on-resistance - significantly lower than the 22 Ω in AC/DC mode. This reduces conduction loss and thermal stress in unidirectional battery-switching applications like EV pre-charge circuits.
What safety certifications apply specifically to VOR1142A6?
VOR1142A6 carries UL 1577 (5300 VRMS isolation), cUL recognition, and DIN EN 60747-5-5 (VDE 0884-5) certification, with VIORM = 890 Vpeak and partial discharge <5 pC. These apply directly to the DIP-6 package variant and are verified per production test methods A and B defined in the safety ratings table.
How does the pinout of VOR1142A6 differ from VOR1142B6?
VOR1142A6 uses DIP-6 with 7.62 mm lead pitch and Pin 3 designated No Connect; VOR1142B6 uses SMD-6 with 2.54 mm pitch and identical functional pin mapping (Pins 1–2 input, Pins 4–5–6 output), but Pin 3 is not present - confirming they share the same internal circuit topology despite differing mechanical form factors.
